O'Brien pair joint favs for Longchamp feature Treasure Beach and Seville have both been installed as 11/4 co-favourites with Ladbrokes for the Grand Prix de Paris alongside Prix du Jockey Club winner Reliable Man. The Ballydoyle pair finished first and second in the Irish Derby and look set to lock horns with the first two home from Chantilly with runner-up Bubble Chic an 11/2 chance. The Longchamp race takes place on Thursday, and Ladbrokes are looking forward to discovering more clues about potential Ladbrokes St Leger horses. David Williams of Ladbrokes said: "It's the first opportunity for punters to weigh up the respective merits of the Irish Derby and French Derby form. We're happy to leave that conundrum to the punters at this stage. "We feel that the Longchamp race could provide some valuable pointers for the Ladbrokes St Leger. Hopefully the race will throw up a result that we can take with us to Doncaster."
